Emerging Infectious Diseases and Travel Medicine

Research Overview

This group leads key research in emerging infection diseases, travel medicine and antimicrobial stewardship. This includes research preparedness platforms for emerging infectious diseases, biobanks and data linkage for infectious disease registries. Dr Thevarajan is the lead investigator in a prospective observational project in APPRISE, Sentinel Travellers and Research Preparedness Platform for Emerging Infectious Disease (SETREP-ID), that rapidly detects and characterise emerging infectious diseases by enabling in-depth data collection, biological sampling and bio-banking. The Platform was activated in the Pandemic with a prospective cohort of hospitalised COVID-19 cases. This collaborative research preparedness platform is funded by NHMRC and APPRISE (Australian Partnership for Preparedness Research on Infectious Disease Emergencies). It was one of Australia’s first research platforms to be mobilised for the COVID-19 pandemic and has led to one of the earliest publications in Nature Medicine in the immune responses to a recovering COVID-19 infected individual (Nature Med Thevarajan et al. 2020). The SETREP-ID protocol is aligned with the International platform, International Severe Acute Respiratory and Emerging Infection Consortium, has facilitated national groups including the Australian paediatric network in collaborative large-scale research and, has a well-characterised COVID-19 biobank that is supporting multiple COVID-19 investigator initiated studies. In addition, the group is involved with qualitative studies on health care workers approach to diseases of high-consequence (Viral Haemorrhagic fevers) and the impact of COVID-19 on healthcare workers.

More about Dr Irani Thevarajan

Dr Irani Thevarajan is an infectious disease physician based at the Royal Melbourne Hospital and Peter Doherty Institute for Infection and Immunity and is in the clinical and infection prevention pillar of APPRISE. In addition to clinical infectious disease expertise, Dr Thevarajan is part of the Anti-microbial stewardship team at the Royal Melbourne Hospital. Dr Thevarajan conducted her PhD in the epidemiology of influenza, dengue virus and japanes encepahlitis infections in travellers and following on from her PhD has been involved with research in emerging and re-emerging infectious diseases. She is the the principal investigator of Sentinel Travellers Research Preparedness Platform for Emerging Infectious Diseases (SETREP-ID) and has led the development of the research preparedness platform that is mobilised to capture early data in the context of a disease outbreak or pandemic. Dr Thevarajan is an Associate Investigator on a University of Queensland funded vaccine grant and MRFF COVID-19 immunological studies grant. She has supervised MPH students, scholarly students and speciality registrars for their college research requirements and published in widely cited journal articles in the area of emerging and re-emerging viral infections.
